investigations have been carried out on the indoor air pollution in .different workshops of food processing plants in iran. in order to evaluate the exposure of workers to the three most commonly used indices of air pollution ten food processing plants representing ten groups of food industry with 2.816 workers were selected. air borne contamination of different origins such cotton seed. barley...
background some human diseases such as tuberculosis, legionnaires' disease and different forms of bacterial pneumonia, coccidioidomycosis, influenza, measles, and gastrointestinal illnesses are the result of exposure to bioaerosols. in addition, they are associated with some noninfectious airway diseases, such as allergies and asthma. objectives in the education hospitals of hamedan university ...
There is nowadays no single fully satisfactory method for VOC removal from indoor air due to the difficulties linked to the very low concentration (microg m(-3) range), diversity, and variability at which VOCs are typically found in the indoor environment. Although biological methods have shown a certain potential for this purpose, the specific characteristic of indoor air and the indoor air en...
To evaluate the levels of indoor air pollution in rural areas of China and their effects on respiratory health, we monitored the indoor (bedroom and kitchen) and outdoor levels of PM10, SO2 and CO in 189 randomly selected households of rural areas, Anhui province, China. We also conducted an investigation of 487 subjects between the ages of 15 – 65 years old with a questionnaire. The PM10 level...
background: the effect of mold fungi to allergic sensitization is not well-known. we aimed to evaluate the role of molds in the relation between indoor environment and atopy in asthmatics. materials and methods:the air samples obtained from 66 stable asthmaticsand 35 control subject’shouses were sprayed into sabouraud dextrose agar. allergy skin testing were performed both groups. the tempera...
Objectives: Many of non-respiratory and respiratory disorders are associated with bioaerosols in indoor and outdoor air. The best conditions for bioaerosols life are high humidity and moderate temperatures, which exist usually in indoor spaces such as the prisons, where density of individual is high. Pathogen spreading centers cause the prisoners health at risk of disease outbreaks through airb...
In this investigation, the performance of an existing heating system of a residential building incorporated with an array of solar thermal collectors was studied. For this purpose, transient systems simulation program model was assembled to estimate the hour-by-hour performance of the existing and the system equipped with the solar thermal collectors in terms of the provided space air condition...
Particulate matter (PM) pollution has raised serious concerns for public health. Although outdoor individual protection could be achieved by facial masks, indoor air usually relies on expensive and energy-intensive air-filtering devices. Here, we introduce a transparent air filter for indoor air protection through windows that uses natural passive ventilation to effectively protect the indoor a...
The indoor air quality is much more matter of concern as relative to ambient or outdoor air quality, especially in the context of human health. However, very few studies have been reported for remediation of indoor ozone by plant species. The main objective of this study is to evaluate ozone deposition velocities and ozone removal effectiveness of three indoor ornamental plant species (Dra...
58 percent of Nairobi’s population live in slums under extremely poor and unhealthy conditions. In these settlements, pneumonia is one of the top causes of health issues and deaths among children and adults, for which indoor air pollution is a known contributor. Yet, the topic of indoor air pollution receives no attention. Regulatory frameworks and budgets for indoor air pollution do not exist ...
